A vector with magnitude 3 points in a direction 160 degrees counterclockwise from the positive x axis.
Write the vector in component form.

-----------------
V = 3*(x*cos(160) + y*sin(160))

.

The component form of the vector V is V = (3*cos(160°),3*sin(160°)). So, vector V has 2 (two) components = 3*cos(160°) and = 3*sin(160°).

Solved and answered.

------------------

Also, the magnitude of a vector IS NOT MEASURED in "points".

It is measured in "units".

Therefore, it is not correct to say "the magnitude of vector V is 3 points".

It is 3 units, instead.
